TOP VULNERABILITY THIS WEEK: Oracle Releases Out of Band Security

Advisory for Java Vulnerability Patched in 2013


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Oracle Releases Out of Band Security Advisory for Java
Vulnerability Patched in 2013
Description: Oracle has released an out-of-band security advisory for a
Java vulnerability that was originally reported in 2013 and patched back
then. Since the original release of the patch for CVE-2013-5838, new
information detailing how the patch was incomplete and could still allow
an attacker to remotely execute code has been made public. In response
to this new information, Oracle has fixed the broken patch and has
release an updated version of Java that addresses the issue. Per
Oracle’s website, “Oracle Java SE 7 Update 97, and 8 Update 73 and 74
for Windows, Solaris, Linux, and Mac OS X are affected.” Users are
advised to update their Java installations.

Title: New Server-Side Ransomware Variant (Samas/Samsam) Hitting Hospitals
Description: Researchers have identified a ransomware variant that
appears to be currently targeting hospitals in the United States. Known
as Samas/Samsam, this ransomware variant is unique in that instead of
targeting individual users through phishing attacks or via exploit kits,
adversaries are compromising systems via external facing JBoss servers
that are vulnerable to compromise and moving laterally within the
network to compromise additional systems. Multiple threat intelligence
organizations have reported on this ransomware variant with detection
being made available to detect and mitigate this threat.

Title: Multiple Cross-site Scripting (XSS) Vulnerabilities in Zen Cart
Patched
Description: Researchers at Trustwave have identified multiple XSS
vulnerabilities in Zen Cart, a popular online shopping cart software
package. Trustwave responsibly disclosed these vulnerabilities to Zen
Cart and worked to ensure all vulnerabilities were properly patched
before disclosure. Zen Cart has release Zen Cart 1.5.5 to address these
vulnerabilities. Additionally, Zen Cart has made available the patches
to address the flaws if patching is not immediately possible.
